Hey there! Nice to meet you!
The AI above appears to have given you an answer for business accounts.
Just in case you have a personal Microsoft account, here's how to cancel your subscription:
Sign in with the same account where you have the Microsoft 365 subscription on account.microsoft.com > go to Subscriptions > Locate the subscription > then select Cancel Subscription.
Please be advised that unless the account owner is able to access the account, subscription cancellation is not possible, and Microsoft personnel cannot retrieve this information.
If you can't find the subscription under your account, you may follow the guide on the official Microsoft website to investigate and locate the subscription from Microsoft on this link:
You may also try contacting Microsoft Support for further assistance in tracking the transaction:
Type "Cancel Subscription" > click "Get Help" > Scroll down to Sign in to Contact Support > Microsoft 365 and Office > Manage my subscription > Confirm > Chat with a support agent in your web browser
If you and the Support Team are unable to find the subscription in all of your accounts, you will need to reach out directly to your bank and request to block all charges from Microsoft, cancelling the subscription on its renewal in the process.
You may also need to request a new payment method.
Thank you for your understanding.
Best regards,
Darhyl
